Thanks for clearing that up.

Sorry about the TIFF, default screen grab on OS X.

Stellar.

Is there any way you could upload your assets?

I can just as easily google and download a random .3ds, but seeings as yours is proven to work I would rather yours. If you don't mind, of course.

Graphics / Extra lines in Text

« on: May 02, 2012, 06:00:20 pm »

I know I have seen posts like this in the past, but I have just looked through the Graphics posts and couldn't find any.

Just wondering if anyone else is seeing extra lines around each character in their text?

I am running OS X Lion, with the latest SFML2 (pulled a couple minutes ago).

Graphics / Re: Text.setString("") crashes on mac

« on: May 02, 2012, 05:53:39 pm »

Texus,

What I have done is extend the sf::Text class, and add setString("something"); in the destructor. There may be some pitfalls, and I understand it s a hack. But it is a workaround that has been seeming to work until the actual bug is fixed.

I have been away for a bit. I have now come across these errors in the build process:

For this case, I certainly see SFMLDIR and SFML_DIR as two different variables.

But it appears that I have SFMLDIR set, no?

If /usr/local contains the directories local and lib, which contain the sfml headers and sfml libs respectively. Wouldn't this satisfy the cake file?

The file you need (I think at least) is FindSFML.cmake and its located in the SFML source dir under cmake/Modules.

I have also tried to set both SFMLDIR and SFML_DIR to: /Users/nick/src/SFML2/cmake/Modules with the same results.


Thanks in advance.

I am not positive I have posted this in the correct place.

I am having an issue getting cmake to generate makefiles properly.

SFML_DIR-NOTFOUND

The location that I have SFML2 installed at is (default) /usr/local.

The location that I have SFML2 sources is: /home/nick/src/SFML2

I have pointed SFML_DIR at:
/usr/local/
/home/nick/src/SFML2/
/usr/local/include/SFML/


They all end up the same:




I have searched the SFML2 source dir for SFMLConfig.cmake and for sfml-config.cmake, but have not found either file.


Thank you for any help!

Targeting Linux. Multiple distros. I develop mainly on OS X, deploy test runs on Linux, usually Ubuntu or Debian.

I will have to look through the SDL code to see what they are doing, and perhaps add that to SFML if time permits.

Thanks for your help!

General discussions / Re: sf::Thread and know if it's running?

« on: April 17, 2012, 07:55:57 pm »

This is off the main topic from the OP, but I feel that I have been called out. I also feel that the OP has the answer to the original question.

If anyone thinks they can be lazy and just toss in a volatile keyword without proper synchronization to take care of strange multi-threading behavior: You are playing a very dangerous game.

If this was aimed at me, perhaps my quick reply painted a distinctly different picture of how I code.

If one thread only reads a value while the other writes it, volatile will be required so that the compiler doesn't optimize away the read operations in the first thread -- because it wrongly thinks that the variable never changes.

Citing from http://kernel.org/doc/Documentation/volatile-considered-harmful.txt:

This is the point that I was trying to make. From what I understand, this is the only reason to use it.

It doesn't make a variable thread-safe, but it is not completely useless.

You are correct. It is not useless. It is in fact far worse, counter-productive.

Not sure where you are going with this one, but seems to me like it's the opposite of your previous quote...

Moral of the story? Proper usage of synchronization objects almost always takes care of compiler optimization issues without completely suppressing all forms of optimization.

This is all with the assumption that there is enough memory on the device that you are coding on to create and use proper sync objects. In the embedded world space isn't a luxury, in fact most of the time it is the challenge. The only place that I have ever needed volatile is on embedded devices. That is when volatile is needed most (In my experience). But then again if you are on a device that you can use all the proper objects that you need, you probably are not optimizing for compilation size, therefor rendering volatile useless. Maybe this is the situation that you were alluding to in the previous quote?

« on: April 17, 2012, 03:04:23 am »

This is completely irrelevant to SFML.

Perhaps this is a bit harsh. In SDL2 I would call

Code: [Select]

SDL_DisableScreenSaver();. I was merely looking for an equivalent to this in SFML.

Perhaps it is completely not possible in SFML, but to say completely irrelevant?

I am trying to use SFML2 in place of SDL2 in our kiosk systems. So, my next task is going to be to disable the mouse - so I am not sure that will work as planned either.

General discussions / Re: sf::Thread and know if it's running?

« on: April 17, 2012, 01:51:02 am »

I use volatile any time I am using a var between threads.

If I am not mistaken, it has nothing to do with atomic writes. More because your compiler can optimize (for binary size) memory mapped variables out of scope. Not so much in C++, since you typically have little reason to optimize your compiling to that degree and there is typically less use of pointers between threads. In the embedded world, it is definitely needed.

A good rule of thumb is when you are running multiple threads, and something isn't getting checked or set, slap volatile on it and clean & build.
